Plot the points on a graph and join them to form a closed figure. two sides that are parallel shows it is a trapezoid
Line perpendicular to a given line is = 1/m
To find m, use m =y2-y1/x2-x1 formula
m = (8-(-3))/(-7-4)
m = 11/-11,
m = -1
Use y= mx+c to find equation of line
Plug in a pair of values,
-3= -1(4)+ c
c= 1
Thus, equation is:
y = -x+1
Equation of line perpendicular to this line is:
y= x+1

Answer:
5 & 5/6
Step-by-step explanation:
length =8W -5
W+ W + 8W-5 +8W-5 = 115
2W + 16W -10
18W-10=115
18W =105
W = 5 and 5/6
